Client side unsigned upload added

[cramhead]

So I've extended your package to include unsigned clientside upload. It's pretty rough and ready, but thought you might be interested. It's available at https://github.com/cramhead/cloudinary_clientside_upload

A sample project, to show how to use it, is available at https://github.com/cramhead/cloudinaryStub
